Yea, just a dyno or two here. Nothing high quality.

A buddy of mine who does some of my photography is a pro cinematographer and we are going to go out when it gets a bit warmer and do a promo video for my car and his brothers 900HP 2JZ VVT-i S2000.

 

Who did your tune? Was it done on a Dyno? Hats off to you for tackling this kind of one-off build!

 

The tune is from TPC themselves that they load on all their cars with this kit. After letting it idle and doing revs to 3k it seems like a very solid tune. I am going to have someone come out once I get my meth kit on and do some more street and dyno tuning.

As for one-off idk about that haha! Thanks

 

Amazing!

 

That it is!

 

Update: Water pump for IC is installed. I ran a line from the battery back to the rear seats area and am using termal rings to connect all electronics back there. I wired it via switch for the on/off capabilities until I get my meth kit. I am going to eventually hav eit set up so it is off when the key is no longer in acc. position but I still have a manual override switch when it is no. If idling in parking lots or letting it warm up, I dont want to have it running

 

Well... It is that time now...

I just drove the car, seems to idle great, and cruising around seems no big deal. It feels a bit hesitant as it builds into boost/full boost (3K-4.5K rpm range or so) and then gets smooth from about 5K to redline.

My IS300 when it ran rich had this similar behavior using a piggyback system, and leaning it out with a proper tune did wonders.

Here is where it gets interesting though. The wideband is placed post cat and post turbo on the downpipe. Now post cats shouldn't have a change on the reading too much, at most maybe .5 on the reading scale. However it at some parts is off the scale lean as in 17/1 or higher. Idle is about 15/1 on the wideband. So the wideband is telling me opposite of how I think it feels and is driving.

Thoughts? commends? Maybe a leak?

 

I did another run with the car last night. It drove out of boost great, however building boost it was still stuttering. I spoke with Tom at TPC racing and he was very nice and great help.

Without giving him any logging information, we narrowed it down to a possible vacuum error with the lines that run out of the throttle body there near the plenum, or a dirty maf which I will clean later tonight.

I pulled the CEL code and it is giving me a P0154 which means "no activity" on the precat o2 sensor, but other places says it is a "too lean" or "too rich" code.

I will check voltage on the o2 sensors and make sure they are operating normally while I am at it.

 

Sounds like a leak or faulty sensor. Well, I hope you will find it, so we can see some great vids on the car, killing other cars on the street

 

If it was better, reach down there and grab a coated header.. Ill reach down and grab my wrapped headed... see who last longer.. prosche owners ...fashion over function...haha

 

Wrapping is for Rednecks with Chevys...

 

Haha.. yeah.. that's its.. has nothing to do with common sense huh???



I see your just another fan boy that promotes whatever he reads without regards to actual real world experience.. tell you what, bring the POS car you have and I’ll leave my p car at home and Ill mess your world up in my redneck Chevy car… whatever race you want to do.. road, track, 1/4... you name it.. we'll do it.. but im betting your just going make some excuses why its wont happen and how its not fair or what ever lame excuse people like you cry about on the internet..


fyi.. Texas 2k14 is 2 weeks away.. ill be around.. will you??


come one and get you some!!!

 

I started from theMAF and worked my way to the exhaust tips.

1) secondary air pump located in left side of bay was unplugged. Oops.

2) some how the o2 sensors on both sides of the cats were very loose. I could spin then with my hand loose. That I think I owe to a buddy helping me.

3) the big one - there was a rip in te hose after the MAF before te turbo letting unmetered air into the car. It was a small 1.5" rip or so but in sure that had a lot to do with it.

I am still looking through everything. Plugs look good, no black or white build up, injectors don't show any leaking, and I don't see anything else major.

I do have a small oil leak on the right side of the car that only leaks when the car is running. It's in the top near the alternator area. Thoughts?

 

The item listed also got unplugged by accident when installed some of the IC piping. Can anyone tell me its function?

 

I keep checking back for updates. Any progress?
